CADAM
CADAM is the open source text-to-CAD web application
CADAM is an open-source “text-to-CAD” web application that turns natural-language prompts into parametric 3D models, targeting a workflow where you describe what you want and the system produces editable geometry. It is designed around a browser-first experience, so users can iterate quickly without installing a heavyweight desktop CAD suite for every experiment. A key idea is that the generated output is parametric and scriptable, enabling repeatable edits and variations rather than a one-off mesh result. The project integrates modern web tooling and a backend stack to manage sessions, model generation requests, and persisted outputs, making it usable as an actual product rather than only a demo. It’s also built to support an agentic workflow, where the system can refine outputs over multiple steps, bridging the gap between intent (“a bracket with four mounting holes”) and precise geometry. -

Open Source Text to CAD Harness
An open source harness for generating CAD models
Open Source Text to CAD Harness is an open-source framework that enables the generation of parametric 3D CAD models using natural language prompts interpreted by AI coding agents. It acts as a harness that converts text descriptions into source-controlled CAD scripts, which are then compiled into geometric models using tools like OpenCascade and build123d. The system emphasizes reproducibility by storing CAD logic as editable code rather than opaque binary files, allowing iterative refinement through agent-driven workflows. It includes a local visualization interface called CAD Explorer for inspecting generated geometry and supports multiple export formats for engineering and manufacturing use. The project also integrates modular “skills” for robotics, motion planning, and manufacturing validation, making it highly extensible. Designed to run locally without backend dependencies, it provides a flexible environment for experimentation and production workflows. -

LeoCAD
A CAD application for creating virtual LEGO models
Design virtual models you can build with LEGO® bricks. LeoCAD has an intuitive interface that is designed to allow new users to start creating new models without having to spend too much time learning the application. At the same time, it has a rich feature set that enables experienced users to build models by using techniques that are more advanced. LeoCAD is fully compatible with the LDraw Standard and related tools, and it reads and writes LDR and MPD files so that you can share and download models from the Internet. It also uses the LDraw parts library, which has over 10,000 different parts and continues to receive updates. Native versions are available for Windows, Linux, and macOS to ensure that users are familiar with the program interface. LeoCAD is open-source, so anyone can contribute with fixes and features, and it is always going to remain free. -

ImplicitCAD
A math-inspired CAD program in haskell. CSG, bevels, and shells
ImplicitCAD is a programmatic CAD program, implemented in Haskell. Unlike traditional CAD programs, programmatic CAD programs use text descriptions of objects, as in programming. Concepts like variables, control structures and abstraction are used, just as in programming. With the explosion of 3D printing, designing 3D objects has become an even more important problem. And it's a complicated one. We need to design complicated objects that precisely interface with each other. And often we don't want to just design a single object, but classes of objects, parameterized by variables. And we need to do this in collaboration. Generally, objects in programmatic CAD are built with Constructive Solid Geometry or CSG. Unions, intersections and differences of simpler shapes slowly build the object. ImplicitCAD supports all this and much more! For example, it provides rounded unions so that one can have smooth interfaces between objects. -
